Google OS tips to export and share feeds for selective folders from Google Reader, here’s how to export feeds from a folder:

http://www.google.com/reader/public/subscriptions/user/-/label/FOLDER(you should replace FOLDER with the actual name of the folder)

Another way to share the subscriptions from a folder is to make it public and to use this link for the OPML file:

http://www.google.com/reader/public/subscriptions/user/USERID/label/FOLDER
(USERID can be obtained from the public page created by Google Reader)
